I've been reading about device polling. I'm wondering if it's worth doing
on a busy website (4,000,000+ hits/month, 45GB+ bandwidth use). I
understand what polling is and how it queues traffic as opposed to the
"old-fashioned" interrupt method, but do you really gain performance-wise?
Are there any pitfalls to enabling it in the kernel? (I understand you
can enable/disable it using ifconfig.) Any gotchas regarding tuning?
(This is a production website. I don't want to cause problems that are
hard to figure out.)
If it matters, I'm running 6.1 RELEASE, GENERIC kernel, Broadcomm GIG
NICs, 3.2GHz processor, 2GB of memory, apache 1.3.*
